【Abstract】 This paper is focused on the transformation of the CT-40. In the transformation, we dismantle all the mechanical control cabinet parts over the servomotor but keep the speed regulator and oil pressure system. Meanwhile, a new computer governing system with PLC, which is the core of the control, and digital electric-hydraulic commutating valve have been used, which can save about 50,000 yuan technical upgrading fund per suit.更多还原
